ELECTRICAL SIGNAL ASSEMBLY Filed June 20, 1947 grwe/wlm Jagfi Williams.

Patented July 12, 1949 UNITED es 2 Claims. 1

This invention relates to an electrical signal assembly particularlyuseful for mounting portions of a signal system for use in ofiices,hospitals and the like, and the prime object of my invention is toprovide a novel electrical signal assembly which can be mounted in theusual electrical outlet box.

Another object of my invention is to provide a novel electrical signalassembly which is simple in construction, inexpensive to manufacture andeffective to operate, and in which the main base or frame consists of ametal stamping.

A feature of my invention is to provide a novel electrical signalassembly in which a plurality of electrical units used in a signalsystem are mounted on a base or frame, and are so arranged and mountedthat the entire assembly will fit in the usual electrical outlet box.

Another feature of my invention is to provide a novel electrical signalassembly which is compact and in which the various parts of the assemblycan be easily reached for repair or replacement.

Other objects, advantages and features of invention may appear from theaccompanying drawing, the subl'oined detailed description and theappended claims.

In the drawing:

Figure 1 is a rear elevation of my electrical signal assembly.

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

Figure 3 is a plan view of the frame after it has been completed as astamping, but prior to bending the various parts.

Referring more particularly to the drawing, my electrical signalassembly is mounted on the back of the usual face plate I, which coversthe electrical outlet box, all of which is usual and well known in theindustry. My signal assembly consists of a frame 2 which is formed froma suitable sheet metal and is stamped in the shape shown in Figure 3,The ears 34 are bent upwardly along the lines 5-45 respectively, and ascrew 1 extends through the face plate I, and through the ear 3 to mountthe frame on the back of the face plate. A threaded sleeve 8 extendsthrough the face plate and through the ear 4, thus mounting the lowerend of the frame 2. With these two attachments, the frame is fixedlyattached to the back of the face plate I. An ear 9 is bent upwardly fromthe frame 2 along the line H] and a coil H is mounted on this car. Thiscoil is part of the operating mechanism of the switch l2.

A li ht socket it is bent upwardly along the line l4 and a signal lightit screws into this socket. The signal light it is positioned back of alens it in the face plate l. One contact of the light 15 engages aterminal I? which extends through the hole I8 in the frame 2. All of theterminals subsequently described are of the same type, that is, theyconsist of a threaded shank and lug nuts threaded to the shank andbearing against each side of the frame plate 2, thus holding theterminal in position.

A switch terminal I9 is mounted in the hole 26 in the frame 2. A secondswitch terminal 25 is mounted in the hole 22 of the frame 2. A pushbutton 23 extends through the sleeve 5, and the inner end of the switchbutton is bifurcated to fit over the pin 25, which is mounted in thehole 25 of the frame 2. In the structure previously described, the frame2 extends substantially at right angles to the face plate I, and thevarious parts of the electrical signal assembly are attached to thisframe and consequently are mounted either parallel to the frame or atright angles to the frame. Therefore, the various units are completelyassembled, and the entire arrangement can be mounted in the usualelectrical switch box. Furthermore, by removing the face plate I, theentire assembly is removed and all of the parts thereof can be viewedand can be replaced, or repaired, as necessary.

Having described my invention, I claim:

1. An electrical signal assembly comprising a frame formed of sheetmetal, an electrical face plate, a pair of mounting ears bent from saidframe, a mounting screw extending through one of said ears, and a pushbutton assembly extending through the other of said ears, said mountingscrew and push button assembly extending through the electrical faceplate, whereby the frame is mounted to the electrical face plate, lightsocket bent from the frame and adapted to receive an electrical lamp,said face plate having a hole therein aligned with the electrical lampand a lens mounted in said hole, a coil bracket bent from the frame, aplurality of electrical terminals mounted on the frame, said framehaving holes therein, each of said holes receiving a terminal, and a pinand terminal mounted in said frame, and engaged by the push button, saidframe having a hole therein to receive said pin.

2. An electrical signal assembly comprising a frame formed of sheetmetal, an electrical face plate, a pair of mounting ears, integrallyformed with and bent from said frame, a mounting screw extending throughone of said ears, and a push button assembly extending through the otherof 3 said ears, said mounting screw and push button assembly extendingthrough the electrical face plate, whereby the face plate is attached tosaid frame, a light socket integrally formed with and bent from theframe, said socket receiving an electrical lamp, said face plate havinga hole therein aligned with the electrical lamp and a lens mounted insaid hole, said frame having a hole punched therein, adjacent thesocket, a terminal fixedly mounted in the hole, said terminal beingengaged by one terminal of the electrical lamp, a plurality ofadditional holes in said frame, a terminal fixedly mounted in each ofthe last named holes, said last named terminals consist-' ing of aswitch operable by said push buttonas- 2,016,515

4 sembly, and a coil bracket integrally formed with and bent from saidframe, and adapted to mount a coil.
